During the last decade, swine producers, veterinary practitioners, and animal health researchers have been economically and scientifically challenged by porcine reproductive and respiratory syndrome (PRRS). This disease ...

A gas liquid chromatographic method was developed for the determination of T-2 toxin in feeds. The T-2 toxin was extracted from feeds with aqueous methanol. A zinc acetate and aluminum chloride solution was used to denature ...

Fumonisins are a group of mycotoxins produced primarily by the fungus Fusarium verticillioides (formerly F. moniliforme), one of the most prevalent fungi associated with corn intended for human and animal consumption. ...

Bovine neutrophils separated from the circulation (bPMN) and from milk (mPMN) of inflamed mammary glands (inoculated with oyster glycogen) were compared for expression of C3 and Fc surface receptors (CR and FcR), and for ...

One group (E, n = 5) of beef bull calves was implanted with estradiol-17$\beta$ (E$\sb2$) from birth to 39 weeks of age. A second group (P, n = 5) received placebo. A third (EH, n = 5) and fourth (PH, n = 5) group of bull ...

Pseudorabies virus (PrV) is an alphaherpes virus that is the cause of one of the most devastating infectious diseases to domestic and international pork industries. Major efforts in the U.S. therefore concentrated in ...

The production simulation model evaluated two regression based strategies: decreased prevalence of poor milking ability (MLK) to <1% via culling over three years, and decreased prevalence of low birth weights (BWT) to 10% ...

Two areas of the epidemiology of the spread of pseudorabies virus among swine herds were examined: a spatial analysis at two levels (the county level and the individual farm level) and a case-control study of pseudorabies ...

The present work was designed to characterize and isolate a soluble A. marginale (noncaudal Florida isolate) antigen derived from culture supernatants and infected erythrocytes. Two immunoassays, double immunodiffusion and ...

This study aimed to determine the morphology of placentome carunular crypts and neutrophil chemotaxis response by cotyledons of normal and retained placentas of dairy cows, and to determine the effects of 5mg of dexamethasone ...

Fowlpox, an economically important disease of chickens, is prevented by routine immunization of birds in endemic areas with an attenuated live Fowlpox virus (FPV) vaccine. However, despite this precaution, outbreaks of ...

The protozoan Neospora caninum is a common cause of bovine abortion, and can also cause disease in dogs. Several aspects regarding its transmission were investigated. Dogs fed experimentally infected calf tissues shed ...

The effect of leptospiral infections on the reproductive tract and mammary gland of domestic ruminants has usually been limited to small numbers of dairy cows or abattoir samples. Additional research is needed to further ...

Previous studies have implicated E. coli endotoxins in the pathogenesis of insufficient milk production in the periparturient sow. Experiment I demonstrated that E. coli endotoxins (4, 8, or 16 mg 055:B5 strain) given ...
